This epistle claims that the Apostle Peter wrote it (1:1). It also claims to follow a former letter by Peter (3:1) that appears to be a reference to 1 Peter, though Peter may have been referring to a letter we no longer have. The author's reference to the fact that Jesus had predicted a certain kind of death for him (1:14) ties in with Jesus' statement to Peter recorded in John 21:18.
The earliest external testimony (outside Scripture) to Petrine authorship comes from the third century.1The writings of the church fathers contain fewer references to the Petrine authorship of 2 Peter than to the authorship of any other New Testament book. It is easy to see why critics who look for reasons to reject the authority of Scripture have targeted this book for attack. Ironically in this letter Peter warned his readers of heretics who departed from the teaching of the apostles and the Old Testament prophets, which is the very thing these modern critics do. Perhaps that is another reason some contemporary teachers question its authenticity. Not all who reject Petrine authorship are false teachers, however. The arguments of these modern critics have convinced some otherwise conservative scholars who retain belief in the epistle's inspiration.
Regardless of the external evidence, there is strong internal testimony to the fact that Peter wrote the book.2This includes stylistic similarities to 1 Peter, similar vocabulary compared with Peter's sermons in Acts, and the specific statements already mentioned (i.e., 1:1, 14; 3:1). In addition, the writer claimed to have witnessed Jesus' transfiguration (1:16-18) and to have received information about his own death from Jesus (1:13-14; cf. John 21:18).
Assuming Peter's reference to his former letter (3:1) is to 1 Peter, he seems to have sent this epistle to the same general audience. That audience was primarily Gentile but also Jewish Christians living in northern Asia Minor (cf. 1 Pet. 1:1). The background of the readers and the situation they faced, as Peter described these, fit such an audience well.3
Peter's reference to his imminent departure from this life (1:13-15) suggests that the time of composition may have been just before Peter suffered martyrdom.4The writings of church fathers place Peter's death at A.D. 67-68 in Rome.5Consequently a date of composition about that time seems most likely. Early church tradition also says Peter spent the last decade of his life in Rome.
"Second Peter is the swan song of Peter, just as 2 Timothy is the swan song of Paul. There are striking similarities between the two books. Both epistles put up a warning sign along the pilgrim pathway the church is traveling to identify the awful apostasy that was on the way at the time and which in our time has now arrived. What was then like a cloud the size of a man's hand today envelops the sky and produces a storm of hurricane proportions. Peter warns of heresy among teachers; Paul warns of heresy among the laity."6
The similarities between 2 Peter 2 and the Book of Jude, especially Jude 4-18, have raised several questions. Did Peter have access to Jude's epistle, or did Jude have a copy of 2 Peter? Which book came first? Did one man use the other's material, or did both draw from a common source? The commentators and writers of New Testament introductions deal with these questions thoroughly. See them for further explanations.7
Suffice it to say that the church through the ages has recognized the end product of both 2 Peter and Jude as epistles that God inspired. As far as which came first, we may never know for sure until we get to heaven. The consensus among scholars now is that Jude probably wrote before Peter (or his agent) composed 2 Peter.8I tend to favor the priority of 2 Peter as do many conservative authorities.9
"Most scholars, in fact, date 2 Peter in the early part of the second century and consider it the last New Testament book to have been written. The author's claim to Petrine authorship, therefore, is part of the phenomenon of pseudonymity' in the ancient world, whereby the authority and tradition of a revered religious figure were attributed to a later work by an anonymous author."10
This quotation reflects the majority of scholarly opinion but not the conviction of many conservatives including myself.
"The purpose of 2 Peter is to call Christians to spiritual growth so that they can combat apostasy as they look forward to the Lord's return."11
